I upgraded to the CarveTight spindle over Christmas. Last week I started noticing a horrible racket and heavy vibration in the flex shaft. I didn't notice any damage to the flex shaft, but ordered a new one anyway. While installing today, I noticed there is probably an 1/8 of an inch up and down play in the chuck itself going up into the z-truck housing. Maybe a 1/16 of an inch or a bit more side-to-side play. Is this normal?

Also on the new shaft, do I need to put the spring from the old shaft into the new shaft? I can pull the new shaft out of the z-truck housing pretty easily even with the ball indent in place.

Getting pretty frustrated. I've had the is machine for 2 years, and I can't use it for more than 2 weeks without something happening...
